Description
Technical field
The present invention relates to a kind of cubing for detection of the gear drill hole location.
Background technology
Gear as shown in Figure 1, have four end-face holes on its end face, four end-face holes are manhole, end-face hole is mainly bolt through-hole, pin-and-hole or fabrication hole, the quantity of end-face hole, diameter, setting position are set as required, also be provided with keyway at the center of gear in addition, the gear that has does not have keyway with keyway, the gear that has, is not limited to above-mentioned form.Position degree for this type of gear end face and keyway detects, usually adopt universal tool-measuring microscope, at first to gather the central point A of two teeth, press again the particular location of rectangular coordinate and each end-face hole of polar coordinate measurement and keyway by image method and axle cutting method, the universal tool-measuring microscope applied range is fit to the detection of any exposed gear end-face hole and keyway.But because the individual tooth of gear all has corner angle, universal tool-measuring microscope can make image data deviation occur owing to the location is inaccurate when gathering reference point A usually, and especially for spiral gear, deviation can be more obvious; Moreover the detection efficiency of universal tool-measuring microscope is low, and cost is high, and the detection of very improper batch production is difficult to realize industrialization.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, detection efficiency is high, cost is low, be fit to the cubing of batch detection location of end surface hole on gear degree of putting.
In order to achieve the above object, a kind of checking fixture for location of end surface hole on gear provided by the invention, comprise body (1), support ring (2), axle (3), register pin (4), location key seat (5), latch (6) and the leg (7) that is used for supporting body (1), described body (1) is fixedly connected with by screw (8) with support ring (2), described axle (3) is passed gear (9) from the top down successively, the axis of support ring (2) and body (1) and axle (3) and the dead in line of gear (9), described location key seat (5) is fixedly mounted on a side of described body (1), described register pin (4) level is passed the top that location key seat (5) reaches described body (1), the spherical head (4a) of described register pin (4) snaps between two teeth of gear (9) gear (9) is located, described register pin (4) and the upper end-face hole coupling that arranges of gear (9) have the latch via hole corresponding with described gear (9) end-face hole on described body (1) and the support ring (2).
During installation, at first with screw body and support ring are fixed together, afterwards both are sleeved on the axle, again with gear set on axle, the lower surface of gear and support ring are fitted, gear is subjected to self gravitation also can not locate to prevent the gear rotation by register pin simultaneously along the axial-movement of axle, and gear is accurately positioned in cubing.Latch inserts on gear end face and body, the support ring and gear end face latch via hole accordingly, if latch can waltz through, then the end-face hole position degree of gear is qualified, otherwise is defective; What end-face holes gear has, and corresponding latch via hole just should be set on body, the support ring, and guarantees that all latches can both be by just meeting the demands.
When having keyway on the described gear (9), this cubing also comprises and the measurement piece (10) of the keyway of gear (9) coupling, has the measurement piece via hole corresponding with the keyway of gear (9) on the described support ring (2).Measure piece mainly for detection of the symmetry of keyway, when having keyway on the gear, can in the face position degree of test side, detect in the lump the symmetry of keyway.
As preferably, described body (1) is square, the dead in line of the axis of the center line of described body (1), support ring (2) and described axle (3), totally three and become circumference uniform distribution along the center line of body (1) on described screw (8), be positioned at the orthogonal distribution of leg (7) of described body (1) below, make integral layout more reasonable.
The periphery of latch via hole is provided with fixedly drill bushing (11) in the described body (1), between described axle (3) and the body (1) anti-rotation fixture block (12) is housed, and described anti-rotation fixture block (12) stretches between support ring (2) and the axle (3).Fixedly drill bushing is set on the body, because the latch via hole on the body and the complete corresponding setting of the end-face hole of gear make body both can be used as location of end surface hole on gear degree of putting cubing, can also be as the part of gear face hole drilling anchor clamps; The anti-rotation fixture block has further prevented from relatively rotating between gear and body, the support ring.
The outer end of described register pin (4) is provided with flexible handle (13), set pin sleeve (14) is housed on the described location key seat (5), the part that described register pin (4) passes location key seat (5) comprise with the section of being threaded of location key seat (5) and with the wringing fit suit section of described set pin sleeve (14).Flexible handle can be adjusted up and down register pin, and the ball joint head of register pin is fixing at various height, to adapt to the gear location of various outer diameter; Register pin is combined the set pin sleeve wringing fit when location key seat is threaded, cause register pin inaccurate to the gear location to prevent thread looseness.
This beneficial effect of the invention is: the spherical head by register pin is decided tooth, in conjunction with support ring, gear in the anchor clamps is accurately located, use again the position degree of latch detection of gear end-face hole, with the symmetry that detects piece detection of gear keyway, have the characteristics such as simple in structure, easy to operate, that detection efficiency is high, cost is low, be fit to batch detection location of end surface hole on gear degree of putting, have wide market outlook.
